Flood Advisory

National Weather Service Anchorage AK

928 PM AKDT Thu May 8 2025



.The River Watch team reports that the breakup front on the 

Kuskokwim River is stalled at the mouth of the Johnson River, with 

strong, intact ice extending downstream. Upstream ice is backing up 

tightly to just below Napakiak, where water levels rose Thursday 

afternoon, encroaching on low-lying roads and structures. Minor 

flooding of these areas of Napakiak is likely. Backwater from the 

ice jam is also elevating water levels upstream to Bethel, reaching 

bankfull conditions and pushing water and ice into Brown's Slough. 

Minor flooding is possible overnight in low-lying areas around 

Brown's Slough, including Alligator Acres, especially during high 

tide.
